摘要： A combined pacing and cardioversion lead system with internal electrical switching components for unipolar or bipolar sensing of electrograms, pacing at normal pacing voltages and cardioversion or defibrillation. In bipolar embodiments, an indifferent electrode, closely spaced to a sensing and pacing electrode, is coupled in common through the integral switching circuitry to a large surface area cardioversion electrode. In these embodiments, pacing and sensing is accomplished through a pair of conductors extending through the lead system to the closely spaced active and indifferent electrode pair. When cardioversion energy is applied to the indifferent electrode, the cardioversion energy is also directed to the cardioversion electrode through operation of the switching circuitry in response to the magnitude of the applied cardioversion pulse. In unipolar embodiments, a distal sensing and pacing electrode is coupled through integral switching circuitry to a large surface area cardioversion electrode. In these embodiments, only a single conductor extending through the lead to the pacing and sensing electrode is required. When cardioversion energy is applied to the pacing and sensing electrode, the cardioversion energy is also directed to the cardioversion electrode through operation of the switching circuitry in response to the magnitude of the applied cardioversion pulse.

摘要： Apparatus and method for stimulating neuromuscular tissue in the stomach. The neuromuscular stimulator stimulates the neuromuscular tissue by applying current-controlled electrical pulses. A voltage sensor detects the voltage across the neuromuscular tissue to determine if the voltage meets a predetermined voltage threshold. A control circuit adjusts the current-controlled pulse if the voltage is found to meet the voltage threshold, such that the voltage does not exceed the voltage threshold. A voltage-controlled pulse may also be applied to the tissue. A current sensor would then detect whether the current on the neuromuscular tissue meets a predetermined current threshold, and a control circuit adjusts the voltage controlled pulse such that the current does not exceed the current threshold. A real time clock may be provided which supplies data corresponding to the time of day during the treatment period. A programmable calendar stores parameters of the stimulating pulse, wherein the parameters have a reference to the time of day.

摘要： An external command device and an internal decoding and verification device are used to non-invasively alter the operating parameters of a programmable device implanted in an animal body. Thus, physiological changes can be easily accommodated by the implanted device. In a preferred embodiment, pulse position modulation is used to externally encode the command information. A resulting string of current pulses generates voltage spikes (in the internal decoding device) through inductively coupled coils. Each incoming data bit is verified and the entire command word is verified. After verification, the decoded command is transferred to a command register for simultaneously altering the selected operating parameters. The internal receiver circuitry may conveniently utilize energy from the induced voltage spike, using passive components for forming an output suitable for processing.

摘要： Apparatus for stimulating neuromuscular tissue of the gastrointestinal tract and methods for installing the apparatus to the neuromuscular tissue. The pulse generator is provided with a switching matrix, and may stimulate the tissue in a time-varying manner by selecting pairs of electrodes and altering the polarities thereof while stimulating the tissue. In addition, a real-time clock allowing a trigger for on and off modes, the time clock could also allow for a trigger to change parameters. Such parameters that could be changed are pulse width, amplitude, duty cycle (amount of time of pulse and time between pulses, or series of pulses), frequency, polarity, choice of unipolar versus bi-polar, and electrode on-off. The electrical stimulation utilizes a plurality of electrodes connected to at least one organ in the gastrointestinal tract of a patient along a peristaltic flow path with each of the electrodes being connected at a different location along the peristaltic flow path. Electrical pulses are provided to the organ from a first set of the plurality of electrodes and second electrical pulses are provided to the organ from a second set of electrodes. The electrical pulses provided are in an independent non-phased relationship for maintaining therapeutic regulation of peristaltic flow through the at least one organ in the gastrointestinal tract while defeating the body's natural tendency for adaption.

摘要： An interrogator for remotely interrogating an internal counter of a scoliosis treatment device. An internal counter of the treatment device is incremented for those periods of time in which the treatment level of the device is in excess of a compliance level. The interrogator communicates with the internal counter by means of two serial data lines. On one data line the interrogator generates a clock signal to the internal counter for incrementing the device and on the other data line the interrogator receives a pulse indicating the internal counter has overflowed. By incrementing the internal counter through a full cycle of its maximum count the counter will retain the count present when it is interrogated. Additionally, by counting the number of, clock counts comprising the period from the overflow signal to the end of a full cycle a duplication of the count in the remote internal counter can be stored in the interrogator and subsequently displayed.

摘要： The bandwidth required for a regularly occurring signal such as a television signal, as received from a signal source can be substantially reduced by not transmitting each and every one of the horizontal scan lines. Rather, firstly, one or more selected lines may be transmitted and, secondly, instead of transmitting the remaining, unselected lines, a signal representing a predetermined arithmetic difference among predetermined ones of the scan lines may be transmitted.

摘要： An improved body function assistance device is provided wherein a microprocessor controls the response of the device to various external physiological events and internal timer events. The microprocessor is adapted for use with the limited energy supply available from a battery by activating internal logic components of the processor only in response to selected events and to perform an operating routine corresponding to the "wakeup" event. At the end of the operating routine, a new set of wakeup events is selected and the internal logic components are deactivated. A further reduction in the average operating current is obtained by providing a plurality of counting rates to minimize the number of state changes during counting cycles. The microprocessor may be provided with a fixed operating routine or may be provided with the capability of actually introducing program changes in the implanted device.
